All of my gemini api key is unavailable (429 error)

I dont’t know when this happen. yesterdy I want to use gemini and it said 429 error. and I went to gemini api key page, nothing on the page, I have to import the project I created months ago and it shows the api key is unavailable, It’s used to be free tier. I created a new project and new api key, it’s also unavailabel. that means my account is being banned right? what happened? I just haven’t use the api key for several days and it’s been banned? I find others also encounter this problem. It’s not a single problem only with me.

same error。。。。。。。。。。。。。。。。。。。

same here. my project and API keys simply disappeared this morning. During the night everything still worked. No support from google side. ALL my app users have no service atm. really frustrating
